Amber and the retired detective Ted E. Bear finally make it to Paper City, following the trail of Amber's missing brother Flint.

But Paper City isn't waiting for them to catch up—new events keep breaking around the investigation, and the Reef King, one of the city's most feared figures, emerges as a significant person of interest. The question of who brought RED to Amber's city inches closer to an answer that may not be comfortable for anyone involved.
